Question

Evaluate using Cauchy’s Integral Formulae, where C is a square
with sides of length 4 centred at the origin:

integral: cos(z)/(z-1)^4

Answer 1

haha, now youre doing math!!!

Answer 2

whats the cauchy integral formula, is it with the line integral business

Answer 3

its the integral f(z)/z-w

where you choose f(z) and w

Answer 4

I'm not sure what to choose as f(z), w=1 as there is a singularity at 1

Answer 5

right, a pole
one sec

Answer 6

what class is this?

Answer 7

2nd year undergrad maths :P

Answer 8

wow

Answer 9

in america?

Answer 10

nope...uk

Answer 11

ahh

Answer 12

you know how to figure it out?

Answer 13

no

Answer 14

This is complex analysis. I know how to figure it out, but I'm currently busy at the moment.

Answer 15

hanky, where i can learn complex analysis

Answer 16

without all the formal rigorous stuff. an intuitive approach

Answer 17

Hmm... I can't really say. There are a few textbooks out there that'll teach you theory... you could just look through them and figure out the computational part of it.
